Physicists have struggled for seven decades with the question of why there is more matter in the universe than antimatter.

In a recent experiment, the Large Hadron Collider (LHC) at CERN produced particles believed to have only existed in the ...

What makes up the matter we perceive in the universe? To start, there are the usual suspects, like electrons, protons, quarks and neutrinos. But if those particles aren't strange enough for you, I'm ...

What do quarks, electrons, and photons have in common? They’re all part of the Standard Model - the theory that helped ...

Neutrino oscillation is weird, but it may be weird in a useful way, because it might allow physicists to probe certain ...

“There’s a lot of meanings for ‘small,’” says Janet Conrad, a particle physicist at the Massachusetts Institute of Technology ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Understanding the universe's building blocks, the Standard Model categorizes particles and explains forces, yet leaves ...

A new study broadens the horizon of knowledge about how matter behaves under extreme conditions and helps to solve some great unknowns about the origin of the universe. An international team of ...
